:1,5,61,305
Greatest Common Factor
We found the factors 810,305 . The biggest common factor number is the GCF number.
So the greatest common factor 810,305 is 5.
Lets's calculate LCM of 347,429
Given numbers has no common factors except 1. So, there LCM is their product i.e 148863
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/148863
Therefore, the GCF of Fractions 810/347,305/429 is 5/148863
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 347,429 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(347,429) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(347,429) x common factors =1 x 1 = 1
LCM(347,429) = ( 347 × 429 ) / 1
LCM(347,429) = 148863 / 1
LCM(347,429) = 148863
